Ampacet, a global masterbatch leader, has introduced ThermProtect™, which utilizes an advanced multifunctional stabilizer technology to address the market need for powerful antioxidant masterbatches designed to be used in PCR-rich formulations. ThermProtect can improve aesthetics, processability, and functionality while minimizing the adverse effects of contaminants in PCR.
ThermProtect joins Ampacet’s R3 Sustainable Solutions products, a growing portfolio of innovative masterbatches designed to support circular economy initiatives and benefit customers, the industry and the planet.
Developed to meet the challenges of materials with higher PCR content, ThermProtect stabilizes polymers subjected to multiple heat histories and contaminants. Contaminants in PCR, such as inks, slips, fillers, catalyst residue and other contaminants degrade both aesthetics and functionality. This degradation manifests itself through viscosity changes, black specks, gels, discoloration, plate out, off-odors and reduction of mechanical properties/embrittlement.
While traditional phenolic and phosphite antioxidants provide thermal stability at moderate temperatures, Ampacet’s advanced technology features high performance antioxidants that provide thermal stability at high temperatures and reduce gel formation in recycled PP and PE. ThermProtect also uses specialty radical scavengers, which react with alkyl radicals to immediately stop oxidation, and acid scavengers, which react with acids to eliminate the degrading effects of inks and other contaminants in PIR and PCR. As a result, customers are able to increase recycled content for rigid and film applications, achieve long-term stability of recycled content, extend the life of polymers and achieve sustainability goals.
The new antioxidants in the range include ThermProtect 1001145-N, which contains high performance phenolic, phosphite antioxidents plus alkyl radical and acid scavengers for recycled polyolefins is used primarily for non-FDA film applications. ThermProtect 1001265-N meets FDA requirements and contains high performance phenolic and phosphite antioxidents, and acid scavengers. .
ThermProtect Antioxidants are designed for PE and PP applications, including blow-molded packaging and products, industrial products, such as garbage bags and can liners, shrink films and carrier bags and building and construction products, such as composite lumber, crates and buckets.
ThermProtect Antioxidants join two ThermProtect PET additives recently introduced to the European market: ThermProtect 7000121-E contains high performance phenolic and phosphite antioxidants to reduce yellowing in recycled PET and is used primarily for injection stretch blow molding (ISBM), injection and extrusion thermoforming processes. ThermProtect 7000119-E contains high performance phenolic and phosphite antioxidants plus a blue toner for even more reduction of yellowing in recycled PET.
